My M500 is actually working perfectly, but I never knew until recently that SSDs do not like power loss. Before installing it in my computer I used it as an external drive for a really short time and then later on I had plenty of hiccups going from Windows 8 to Windows 10. So this is my power loss count so far:
174 Unexpected Power Loss Count 36 Unexpected Power Loss events
36.
The M500 is suppose to have power loss protection, but what concerns me is this thread among others: http://forum.crucial.com/t5/Crucial-SSDs/Crucial-M500-MCT480M500SSD1-not-writeable-any-longer/td-p/167882
So do I only have 31 more chances left? I'd like to use this SSD for 5 years, but Windows isn't always stable (or maybe it will be, I have no way of knowing). However, there is one difference between that thread and my situation. Their computer was shutting down incorrectly every single time, where as mine are/will be more random. Does that make a difference to the firmware/drive? Does anyone knowing the exact conditions needed for read only?
Here is the rest of my drive info from Storage Executive:

I just want to know how careful I need to be. Thanks!
